Wi-Fi networks use a radio signal that can be blocked or weakened by any number of construction materials inside of a building. These barriers are a likely reason that a Wi-Fi signal is not penetrating as far as it should be. The table below lists common physical barriers and the effect that they have on your signal. To get better performance through these physical interferences, try moving your router to a different location and try to keep the path from your router to your mobile devices free and clear.

Many household devices emit signals on the same frequency that most routers use. All of these devices running on the same frequency can result in WiFi interference. These devices include microwave ovens, cordless phones, baby monitors, garage door openers, satellite dishes, Bluetooth devices, neighbors’ wireless devices, etc.
